The act of a computer software progress bar (percent complete indicator) that gets stuck at 99% or 100% or even worse wraps back around to 0% and starts all over.

Ted: "Hey Ed, are you ready to go? We're waiting!"

Ed: "Sorry, I went to apply these Adobe and Microsoft software patches and I *thought* they were done but now I am stuck in Progress Barf hell because someone needs to teach those bastards what the definition of 100% complete actually means!!!! This progress bar just keeps wrapping around, not sure why they even bother, it should just show a picture of a dude with a gun to his head going 'click click click'!"
